Generally, there is no update. You only need to review it again to update the itinerary. The travel code stays in the same province and city for more than four hours, and the location of the mobile phone travel code is updated. The communication travel card can be used to inquire about personal travel within the first 14 days at home and abroad, and the cities visited before 14 days are not displayed. If the travel code has been scanned for 14 days, and this field is still displayed, it is usually not updated. You only need to watch it again to update your itinerary.

How do you know travel itinerary code 14 days where have you been?

Trip code is implemented according to the communication service provided by telecom operators.

As we all know, the normal communication services of mobile phones (call, SMS, Internet access) are realized by the communication base station of operators. The communication base station is what we call a "signal tower". With the cell tower, our mobile phones will have a signal.

Each of us has our own ID number, and the ID number is unique. We can find a person accurately through the ID number. Similarly, each communication base station also has its own "ID number" (base station number), and the base station number of each base station is unique. With the base station number, you can quickly find the location of this base station.

The working principle of trip code is to determine the location we have experienced according to the base station signal received by our mobile phone within 14 days, thus listing our approximate trip. For example, Zhang San received signals from two base stations in a certain place in Hebei 14 days, and the base station numbers were 12345/23456 respectively. In this way, when applying for his own travel itinerary code, he must first authorize the operator to inquire, and then through the two base station numbers, he can roughly know that his travel itinerary is somewhere in Hebei. There is another situation. For example, if you drive from Shijiazhuang, Hebei Province to Beijing, your travel itinerary code will include Baoding, Hebei Province. But in your mind, you have never been to Baoding at all. Because you passed Baoding on your way to Beijing, your mobile phone received the signal from the base station in Baoding area, so there will be a record of Baoding area in your trip.
